One of the fans in our 5+ year-old HP Pavilion was dying. I opened up the case and decided it was the CPU fan. I ordered a Thermaltake TR2-R1 to replace the stock heatsink and fan. That worked like a charm except that it was the fan on the GPU that was dying (now fixed), a fact I could have discovered if I had a better ear or had I been more careful in my original diagnosis. Live and learn.
Since I installed the TR2-R1, I am getting a false "CPU fan failure error" on startup. The fan is working on visual inspection. I can use "F2" to bypass the error, and fan speeds and temperatures are normal when checked with SpeedFan. When I momentarily plug the old stock heatsink and fan into the mobo, the machine boots fine. It seems beyond question that the problem is the mobo is not sensing the new fan properly.
The BIOS does not have an option to disable the fan sensor, which was still true after I upgraded (probably because this is all proprietary HP stuff). The mobo is an old ASUS model that the company made for HP (A8AE-LE), so very little support or information is available for it.
I am about to give up and just reinstall the old fan and heatsink. The new one is much quieter and would be nice to keep. If anyone has any suggestions, that would be most appreciated. Further specs:
